I Am trying to upload a Arduino file into the silabs.com/products/develop … cp-drivers , I try with MAC 10.13 and in another Machine with Mac 10.9 and Windows 7 and always have the same problem after choosing Arduino Pro-mini / ATMega328P and the corresponding Serial Port, when I try to upload the file I get the following error:

Arduino:1.8.5 (Windows 7), Tarjeta:“Arduino Pro or Pro Mini, ATmega328P (3.3V, 8 MHz)”

Hi,

You can try the following :

]Hold down the Reset button /:m]
]Continue to hold Reset while selecting Upload /:m]
]When it says Uploading, release the Reset button/:m]
If this doesn’t work, try to choose “Arduino Duemillanove w/ ATMega 328” as a board in Tools -> Boards.

You can take a look at these forum posts which discuss this issue :

Hi

Thank you for answer, yes If I configured as "Arduino Duemillanove w/ ATMega 328” and do the reset trick then it works a least I get the word “subido” by other hand I order a FTDI FT232RL USB to Serial, that seams moreappropriate, but I didn’t receive yet.
